In S4 HANA, for materials with a single source of supply, the arrival of the Automatic Sourcing checkbox means that source list maintenance is no longer necessary. Users simply need to activate this checkbox in the purchase info record (PIR). The MRP run generates purchase requisitions and assigns the source of supply based on the Automatic Sourcing checkbox in the PIR. However, to allow a source of supply for materials with more than one source of supply and allow a supplier to be blocked for a specific period, the source list can still be used in S4 HANA.
Users can enable the Automatic Sourcing checkbox in ME11 / ME12 - Purchasing Organization Data 1 view

If you are maintaining a purchasing info record and you select this checkbox in the info record details, the system takes this info record into consideration when creating purchase requisitions during the planning run.
